# Widely adopted coding conventions

* [PEP8](https://www.python.org/dev/peps/pep-0008/)
* [PEP20](https://www.python.org/dev/peps/pep-0020/)
* [Google Python Style Guide](https://google.github.io/styleguide/pyguide.html)
* [DRY principle](https://en.wikipedia.org/wiki/Don%27t_repeat_yourself)
* [Clean Code: A Handbook of Agile Software Craftsmanship](https://www.amazon.com/Clean-Code-Handbook-Software-Craftsmanship/dp/0132350882)

# Extensions, exceptions and customization

* Preferred order of attributes inside class: class NAMED_CONSTANTS, class data attributes, `__init__()` if present, `__magic_methods__()`, `@properties`, overridden private methods, private methods, overridden public methods, public methods. The order of the methods may be changed in favor of code readability as an exception.
* Only strict dependencies should be used in requirements.txt and setup.py files (meaning: third-party-package==x.y.z, where "x.y.z" is exact version number of python package "third-party-package"). This requirement applies to direct and transitive dependencies (meaning: if "third-party-package" depends on "another-package", then requirements.txt or setup.py should explicitly contain "another-package==a.b.c", where "a.b.c" is a version of "another-package" obtained with `pip freeze` command right after "third-party-package" installation). This will prevent accidental errors on fresh installation due to backward incompatibilities of newest dependencies versions which are installed if strict version requirement is not set.
